Lists - detailed support notes

Lists are partially implemented. Here's what works and what doesn't.

What works

Ordered and unordered lists

Basic list items with inline content work fine, including:

• Nested lists (using different marker levels like *, **, ***)
• Checklist items ([x], [ ])
• Multiline text that wraps within a list item
• List separators (both // line comments and [] block attributes)
• Multiple consecutive + continuations in the same item
• Open block (--) wrappers for grouping multiple blocks in a continuation

Description lists

I've implemented basic description list support with several features:

• All standard delimiters (::, :::, ::::, ;;)
• Principal text (inline text immediately after the delimiter)
• Explicit continuation (+) for attaching block content
• Auto-attaching ordered/unordered lists to description list items (even with blank lines before the list)

What doesn't work

Ancestor list continuation

• No ancestor list continuation (attaching blocks to parent list items with blank lines before +)

Why these limitations exist

The model supports block attachments (ListItem has both principal: Vec<InlineNode> and blocks: Vec<Block>), and most list features work correctly. The remaining issue is:

• Ancestor list continuation (blank line before +) isn't supported - the parser attaches continuations to the last nested item rather than the parent
